Rolling Cache Limit

Recommended Posts

You omitted the part immediately before the part you quoted where he's talking about creating a cache hundred or thousands of GBs. Essentially he's saying there's a point of diminishing returns once you start making the rolling cache size bigger and bigger, hence why a few sentences earlier he recommended 8-32GB.

I'll never growth indefinitely independently on the size, because it's like a moving average, new data is coming in, new data is going out, your cache will never grow over the limit you set.

Just want to point out that when update time rolls around please don't forget to delete the rolling cache file. If you dont and that particular airport or scenery gets an update there may be a conflict. Figured that out shortly after the last update where i did not delete the cache file and the airport was updated in the service update (LSZH). Got two ctd's the moment i tried to go to exterior view. Deleted the cache which probably had old and conflicting data and all was well.

Zero unless you have a very slow internet connection.

I've tried big and small caches and found them to be of no benefit like many others have.

 

Same here. I have 100 Mbpx internet which is slow but not very slow. Rolling cache of any size makes no difference in loading times or stutters as far as I can tell. So about 6 months ago, I just turned it off.

I try it once when the sim was released, I didn't notice any difference at all and haven't used it since.

If you have enough RAM, create a RAM Disk and put your rolling cache there.  Two benefits: 1.) RAM is much faster than even the fastest M.2 drive.  2.) NVMe drives do have a lifespan, and running the cache in a RAM Drive reduces the amount of data being constantly written to a physical drive, thus extending it's lifespan.

But if you turn off your PC the data will be lost?

IMDisk gives you a setting to store an image file when the computer is off.

Correct.  However, I am currently running a 16 gb cache atm purely for flying round in circles admiring certain areas of photogrammetry.  I'm not sure I'm seeing much of an improvement though and may turn it back off.

I have upgraded to 500 mbs internet from my previous 50 mbs connection (free of charge upgrade) which I hope will help things though still not sure what speed the MS servers are pushing out.

I no longer bother with a rolling cache. What I did notice though was I seemed to get less stutters if the rolling cache was not on my Windows drive.

yeah, I agree.  Luckily I have 2 nvme drives and can put the cache on the other one.

Just guessing here but I wouldnt be surprised that if you have rolling cache disabled some of the data that is streamed from the internet is still written to a temporary file or files before being processed by the sim and then re-written over and over.

Rolling cache will be useful if you often fly to or from particular airports. You should see the flight loading in noticeably quicker.

Rolling cache is definetly not only for photogrammetary. I mostly fly in areas that don't have photogrammetery and I find the cache beneficial.

To guage the size of cache needed simply open the data section in the options menu and note the amount of data used after you have flown for a while with the cache on. 16 Gigs seems about right for my usage.

In what way? I've never observed any benefits from either cache.

Whenever you revisit the same airport the scenery renders immediately even in the world map. Try it for yourself to see if it makes a difference for you. It certainly does for me where the closest Microsoft servers are a 10 hour flight away in real world distance.

I'll give it another go.
